2 IMI HEIMEIER / Design-Edition / Design-Edition Design-Edition The sets are an elegant solution for e. g. design radiators. A sublime effect will always be achieved with the Design-Edition white or chrome edition. Together with the thermostatic head DX the result will be such an attractive finish where everything fits together. Key features > > Four different sets in white RAL 06 or chrome > > Covered connections to radiator and pipe for elegant design > > Elegant thermostatic head DX with closed graduation cap and locking ring cover > > V-exact II precision-presetting for precise balancing Technical description Design-Edition Sets with thermostatic valve body, radiator lockshield and thermostatic head DX. There are sets in 4 different versions in each case in white RAL 06 (valve bodies powder-coated) or chrome plated available: Straight Angle Double angle, connection right Double angle, connection left The body, which is made of brass, is designed for connection to a threaded pipe, or in conjunction with compression fittings, for connection to copper or precision steel pipes. Permitted operating temperature TB C. Permitted operating pressure PB bar. Thermostatic valve body with integrated stepless precision presetting and white protection cap. The flow of the presetting can be easily and precisely set with a key. The selected value can be read on the front of the thermostatic insert. With the key, only a specialist can create or change the setting. The stainless spindle is equipped with a double O-ring sealing. The outer O-ring is replaceable under pressure. The complete thermostatic insert can be replaced with the fitting tool without draining off the system. Radiator lockshield for shutting off, draining off and filling. Can be shut-off with a hexagonal key SW. A drain-off and filling device for / hose connection is available A drain-off and filling device for / hose connection is available as accessorie. Thermostatic head DX Liquid-filled thermostat. High pressure power, lowest hysteresis, optimal closing time. Stable control behavior even in the case of small calculated p-band variation (<K). Meet all requirements of the German EnEV and DIN V Setting range 6 C to 8 C. Valve stroke limiter. Setting numbers to. Frost protection 6 C. Max. sensor temperature 0 C. Hysteresis 0.4 K. Water temperature influence 0.7 K. Differential pressure influence 0. K. Closing time 4 min.

3 Construction Thermostatic valve body. Long-life double O-ring sealing. Precise regulating part for accurate V-exact II stepless presetting. Strong return spring in combination with high locating force ensures that the valve does not slacken off over time 4. Thrust piece for draining off. Shut-off cone Lockshield Application The Design-Edition Sets are an elegant solution for e. g. design radiators. A sublime effect will always be achieved with white or chrome edition. Together with the thermostatic head DX the result will be such an attractive finish where everything fits together. The radiator and pipe connections are completely covered. Every set contains also a cover for the thermostatic head locking ring. The thermostatic valve body is fitted with the V-exact II technology for safe presetting as standard. The lockshield makes possible the individual shut-off, drainoff and filling e. g. of radiators in order to carry out painting or maintenance work, without having to shut down other radiators. Sample application

4 IMI HEIMEIER / Design-Edition / Design-Edition Noise behaviour To ensure low-noise performance, the following conditions must be met: On the basis of experience, the differential pressure over the thermostatic valves should not exceed about kpa = 0 mbar = 0. bar. If in designing the system, higher transient differentials might be experienced in the part-load flow range, differential pressure control equipment such as a STAP Differential Pressure Controller or Hydrolux bypass valves can be used (see diagram for noise characteristic curve). Mass-flow must be correctly adjusted. The system must be completely deaerated. Notes To avoid damage and the formation of scale deposit in the hot water heating system, the composition of the heat transfer medium should be in accordance with the VDI guideline. For industrial and long-distance energy systems, see the applicable codes VdTÜV and 466/AGFW FW. A heat transfer medium containing mineral oils, or any type of lubricant containing mineral oil can have extremely negative effects and usually lead to the disintegration of EPDM seals. When using nitrite-free frost and corrosion resistance solutions with an ethylene glycol base, pay close attention to the details outlined in the manufacturers documentation, particularly concerning concentration and specific additives. The thermostatic valve bodies can be used with all IMI Heimeier thermostatic heads and IMI Heimeier or IMI TA thermal or motorized actuators. The optimal tuning of the components guarantees maximum safety. When using actuators from other manufacturers, make sure that the pressure power is appropriate for thermostatic valve bodies with soft sealing valve discs. Operation Presetting The presetting can be selected steplessly between and 8. There are 7 additional marks between the preset values, thus enabling exact setting. Setting 8 corresponds to the standard setting (factory setting). The technician can undertake or change the setting with the setting key or spanner ( mm). This ensures unauthorised persons cannot tamper with the setting. Plug the setting key or universal key into the valve insert and turn until it engages in position. Turn the index of the desired setting value to the index figure of the valve insert. Withdraw the key. The setting on the valve insert is visible from the actuating direction (see fig.).
